I agree! But tell the Chevy boys that chit. They think the 5&7 swap unlocks another 100HP. And that ain't no joke. ....but then, most of them think addin chrome valve covers add 20HP too, so........
Engine masters did a test of the firing order swap. It's been a while since I saw it, but if I remember correctly it made...... nothing. Maybe 5 hp.
Edit: watching the episode right now. Will report back.
